Clevite CB-1638P-10 P-Series High Performance Rod Bearing Set

The Clevite CB-1638P-10 is a high-performance connecting rod bearing set designed for engines operating at extremely high RPMs. These P-Series bearings feature enhanced eccentricity and specialized construction to prevent bearing failure under severe racing conditions.

Key Features:

• P-Series design with maximum eccentricity for extreme high-RPM applications
• Hardened steel back construction for superior strength and fretting resistance
• Reduced overlay thickness to prevent overlay fatigue and "hen tracking"
• High crush design ensures maximum retention in the rod bore
• TriMetal bearing construction with lead-tin-copper overlay
• Meets or exceeds OEM standards for strength and durability
• Sold as paired sets (two bearing halves for one connecting rod)

Application Notes:

P-Series bearings are specifically engineered for engines experiencing severe rod bore close-in at extremely high RPMs, typically indicated by near-complete parting line contact. The increased eccentricity design helps maintain proper oil film thickness and prevents bearing surface polishing and smearing caused by oil starvation. These bearings are ideal for competition engines, drag racing applications, and any high-stress environment where standard bearings fail to maintain adequate clearance.

Installation Requirements:

For a complete engine rebuild, order one set per connecting rod. A 6-cylinder engine requires a quantity of 6 sets; an 8-cylinder engine requires 8 sets. The .010 suffix indicates this bearing is designed for crankshafts ground .010" undersize. No flash plating on the steel back ensures optimal seating during installation.

Note: Each set includes two bearing halves for one connecting rod assembly.
